Answer to Question #315809 in Python for Nadipally venkatesh Guptha

Question

Create a program that will allow the user to easily manage a list of names.

You should display a menu that will allow them to add a name to the list, change a

name in the list, delete a name from the list or view all the names in the list.

There should also be a menu option to allow the user to end the program. If they

select an option that is not relevant, then it should display a suitable message.

After they made a selection to either add a name, change a name, delete a name or

view all the names, they should see the menu again without having to restart the

program. The program should be made as easy to use as possible.

Answer 1

choice = ''
names = []

while choice != "q":
    print("\n[1] Enter 1 to add a name to the list.")
    print("[2] Enter 2 to change a name in the list.")
    print("[3] Enter 3 to delete a name from the list.")
    print("[4] Enter 4 to view all the names in the list.")
    print("[q] Enter q to quit.")


    choice = input("\nWhat would you like to do? ")
    
    if choice == '1':
        print("\n Enter the name: ")
        name = input()
        if name in names: print("\n This name is already in the list! ")
        else:
            names.append(name)
    elif choice == '2':
        print("\n Enter the name: ")
        name = input()
        if name in names:
            print("\n Enter the new Name: ")
            for i in range(len(names)):
                if names[i] == name:
                    names[i] = input()
    elif choice == '3':
        print("\n Enter the name: ")
        name = input()
        if name in names: names.remove(name)
    elif choice == '4':
        print(*names, sep = "\n")
    elif choice == 'q':
        print("Program end")
    else:
        print("\nI don't understand that choice, please try again.\n")
